KAAAAHBS bro. Do NOT buy a Mars blurple. Get Citizen, Vero, Cree CXB, Luminus and a Mean Well HLG driver or 2. Or almost complete Autocobs. Get a few of those running. 50v COBs at 1050ma is about 52w each and they are badass. You can run 3 or 4 off a HLG-240c-1050 constant current driver in series.....which can be had for USD$55 at the right spot with shipping.
Cool COB stuff:
* Extremely modular
* Very expandable
* Best tech on the planet for lights
* ULTRA efficient
* Heat is minimal
* PAR values off the charts
* They last FOREVER (almost)
* Mix and match K° temperatures
* Totally Affordable
* Everybody is doing it
* AFN approved
As you can see, COBs or KAAAAHBS are where it's at for lighting in 2018 as of now. You could get a Mars Hydro with cheap garbage Bridgelux low binned LEDs and no name drivers and WISH you bought some COBs when it shits the bed....or just skip the whole blurple Chinese junk game and get some real state of the art lights. $500 will go a LONG way if u can do some VERY minimal DIY. One grow with COBs and you will be on the KAAAAHB train. Just ask ANYONE on here who is using legit cobs. Not a peep other than straight love. They are THAT good. Done. Peace.
